I honestly wouldn't bother with the 4l80e, more headache than it's worth.what upgrade should i do to my trans, i was thinking about swaping it to the 4l80e is that posible to just make a direct swap. yall have to forgive me im kinda new to the newer trucks.
listen please....PSI means poop. its just measurement of restriction. if more psi was better then i would toss on a 50mm turbo on my truck and over spin the turbo just to say i made 40psi but in real world the power would be nothing.Im really not sure how much psi yet my brother is putting out 38 psi on is evo, but i dont think it could stand that much. I do plan on changing the valve spring and i was wanting to put a different rocker arm ratio on it but i dont know if that is a good idea with the turbo. And who is the best to get a really good tune, i thought nelsons cause i live just outside houston and they are in san antonio so they are ferly close but if there is better i would rather do that.
